Anybody here know anything about allisons. I'm building a truck with a hopped up 5.9 Cummins. Trying to decide what tranny to go with. I'm thinking 540, 542, or 545. I don't know the differences in the 3. Motor should be 800 ft-lbs torque or more. Can a 500 series be made to handle that much or will it take a 600 series. Thanks
